Problem using fckeditor

Topics: Business Logic Layer, Controls
Nov 30, 2007 at 6:59 PM

i'm trying to get the fckeditor working because i need more control over the files (images / videos) etc. on the blog. I did the steps noticed in the wiki entry und some more, because the documentation does not explain all steps. So, i've the editor working, but if i want to browse the server for images from the fckeditors image gallery i get an error: "The server didn't send back a proper XML Response." I've modified the CompressionModule.cs like explained in the docs. But i doesn't work. What can i do to get the fckeditor working?

Exactly the same case here. Did all the steps explained, and not explained, on both sites, but I get the same error message.

Hi again,

Nobody else using fckeditor here?

I changed to fckeditor for the image browsing function. Is there any other application that might be used together with the built-in text editor for image/file browsing and handling?

here is what i did to make it work. I provide all steps to have a complete documentation.
"Webroot" is the directory where you installed in. You should change the web.config
in the last step, because you have to restart your application anyway.

  • Download the FCKEditor main package at
    • Extract the zip file to your webroot. You now have a folder fckeditor in your webroot.
  • Download the FCKEditor.NET package at
    • Extract the zip file to a temporary folder.
    • Copy FredCK.FCKeditorV2.dll from {temporary folder}\bin\Release\2.0\ to the \bin\ directory of your webroot.
  • Create a folder "userfiles" in your webroot. Add write permissions to this folder for the Network Service account (Windows Server 2003).
  • Switch off HTTP compression in the blog settings
  • add_entry.aspx ({webroot}\admin\Pages\):
    • add <%@ Register Assembly="FredCK.FCKeditorV2" Namespace="FredCK.FCKeditorV2" TagPrefix="fck" %>
    • replace <Blog:TextEditor runat="server" id="txtContent" TabIndex="4" /> with <fck:FCKeditor id="txtContent" runat="server" BasePath="/FCKeditor/" Height="700" Width="800" />
    • remove upload fields (txtUploadImage, txtUploadFile)
  • add_entry.aspx.cs ({webroot}\admin\Pages\):
    • replace txtContent.Text with txtContent.Value
    • remove all references to the old upload fields (txtUploadImage, txtUploadFile)
    • the function SizeFormat() can also be removed
  • fckconfig.js ({webroot}\fckeditor\):
    • set _FileBrowserLanguage to 'aspx'
    • set _QuickUploadLanguage to 'aspx'
  • config.ascx ({webroot}\fckeditor\editor\filemanager\connectors\aspx\):
    • you have to implement a session check in CheckAuthentication() or just return true (not recommended)
  • Set enableSessionState="true" in the <pages> section in web.config

Can someone give me a hint how to implement the session check in the CheckAuthentication() method?

Whops... it was actually FreeTextbox that I have been wanting to use, but no one have managed to get that to work with BE, right?

In this case you will have your image uploaded but at the default directory fck use. One thing I'm currently struggling on is the possibility to let fck reads on app_data folder and so share the same path MetaWebLog Api use.
Any idea for thi?

I met the same error.When I delete "CompressionModule" from web.config,it's ok!

add this to appsettings node
<add key="FCKeditor:UserFilesPath" value="~/App_Data/files/" />

To implement CheckAuthentication, in config.ascx, just:

        return System.Threading.Thread.CurrentPrincipal.Identity.IsAuthenticated;

Ok i have followed these steps in version1.6  but have an isse with:

add_entry.aspx.cs ({webroot}\admin\Pages\):

  • replace txtContent.Text with txtContent.Value

so when i replace txtContent.Text i get 10 errors because txtContent.Value is not specified anywhere
